Specific embodiment
For the technical solution of the utility model is more clearly understood, specific embodiment is practical new to this with reference to the accompanying drawing
Type is described further.
As shown in Fig. 1, according to a kind of hydrochloric acid equipment for purifying of the utility model embodiment, including evaporator 1 and purifying
Tower 2,1 outer surface of evaporator are equipped with steam delivery port 11 and steam outlet 12, pass through 13 He of steam conveying pipe
Steam vent tube 14 is connected with each other evaporator 1 and purification column 2, and 14 bottom of steam vent tube is arranged equipped with waste liquid
Pipeline 141 is let out, the waste liquid discharge conduit 141 is equipped with waste liquid and drains valve 142, and the 2 top outer side of purification column is equipped with
Rupture pressure disc 21 connect at the top of the purification column 2 with cooling tower 4 by jet chimney 3, and 4 bottom of cooling tower, which passes through, gathers
Flow tube road 41 is connect with receiving tank 5, is connected at the top of the receiving tank 5 by receiving tank waste discharge pipeline 52 and exhaust gas treating tower 7
It connects, bottom is equipped with emptying pipeline 51, and the emptying pipeline 51 is equipped with emptying valve 511, the 51 outside table of emptying pipeline
Face is connected with discharge pipe 53, and the discharge pipe is equipped with outlet valve 512, is equipped with exhaust gas at the top of the exhaust gas treating tower 7
Discharge outlet 71, bottom are discharged into pipeline 62 by raffinate and connect with raffinate bucket 6, and 6 bottom outside surface of raffinate bucket passes through residual
